I just felt like it, so I went to the supermarket and bought a packet of sausages. The batter is a standard pancake / yorkshire pudding mix.
Make a hole in the flour, add the eggs and milk and whisk until no lumps. Add s&p and herbs, I used thyme.
Heat oven to 200ºC, roast the sausages in 2tbsp oil for 5-10mins. Pour the batter into the baking tray and bake until golden, around 40mins.
I think the tray was too large so the batter was too spread out, making it a bit burnt at the bottom. In retrospect I should have bought two packets of sausages; or used a smaller baking tray.
Seasoning was nice. Crunchy on the bottom and soft in the middle. And sausages.
